Fractional skin resurfacing From lasers and contact radiofrequency to minimally invasive microneedles The demand for new procedures delivering visible clinical improvements with reduced downtime, has led to the development of fractional lasers13–14
. Instead of treating an
entire skin area, these lasers treat a condensed matrix of small ‘islets’ of tissue leaving intact skin in-between. Healing is initiated from these intact skin areas resulting in reduced downtime and reduced complications. Since the introduction of the first fractional laser system, a myriad of ‘fractional’ laser systems, mostly based on CO2
and
Erbium:YAG laser technology, have been developed and cleared for marketing worldwide15
. In recent years, several fractional RF systems have been
introduced that allow controlled fractional skin resurfacing by employing a matrix of miniature RF electrodes placed in contact with the skin surface. In addition to the
epidermal effect, fractional RF systems allow for an enhancement of the dermal layer via volumetric heating leading to an effective micro-ablative skin resurfacing and the improved appearance of wrinkles, fine lines, and acne scars. Recently, new devices employing minimally invasive
bipolar micro-electrodes that are percutaneously introduced into the skin, were introduced to the market for the treatment of wrinkles and skin laxity16–19
. Published
studies revealed that such treatments induced an active dermal remodeling process including neoelastogenesis and neocollagenesis with an intact epidermal layer16–19
